Greetings all.
Yesterday I was making random reading on the handbook and look at booting process. An idea struck me - it is possible to make silent boot - no boot loader, no dmesg, cut beastie menu so no options be available on boot, - nothing, just black screen, and login prompt. Dig a little and ..
echo this in /boot/loader.conf

Code:

disable_beastie="YES"
autoboot_delay="-1"

echo this in /boot.config

Code:

-nmq

touch a little /etc/gettytab to remove im= - the welcome banner
and..job done.
Almost...
BTX loader version is echoed on boot - after system is up and running half of btx message is replaced with login prompt.
How to remove BTX loader message ?
